The solar-powered tech that generates water out of desert air

It might seem counter-intuitive, but Coleridge’s famous line from the Ancient Mariner could also apply to the desert. Even in some of the driest places on earth, the air holds thousands of litres of fresh water that have remained tantalisingly inaccessible. Until now. Scientists at MIT and the University of California at Berkeley have created a device that can suck water from the air. Even better: it’s solar-powered. So, even in the most remote, arid deserts it can harvest drinking water from the atmosphere.
